Description
Technical field
The present invention relates to car steering accessory system, more particularly to a kind of Vehicular turn based on ADAS technologies
Detecting system.
Background technology
Senior drive assist system (Advanced Driving Assistant System, ADAS), is a kind of
For gathering related data in vehicle traveling process, and then realize that auxiliary drives, improves the functions such as security
System, its representative enterprise is the Mobileye of Israel.So-called auxiliary drives, i.e., on the run
Lane departure warning (Lane Departure Warning, LDW), frontal collisions warning (Forward are provided
Collision Warning, FCW) and pedestrian impact warning etc. warning function.In LDW deviation sides
Face, usually using camera come monitor vehicle whether run-off-road line, occur deviation scene have two kinds
May：One kind is that driver plays steering indicating light and active lane change, is now considered as safety behavior；Another is to drive
Member does not play steering indicating light and occurs deviation, is now considered as hazardous act.The first safety behavior is normal behaviour
Make, it is not necessary to alarm, and second of behavior should then provide alarm to remind driver to note in advance.
Drive recorder of the country with ADAS functions almost employs pseudo- LDW algorithms at present, and it is only capable of obtaining
Deviation situation is taken, due to lacking vehicle active lane change direction information, it is impossible to active lane change and dangerous change
Road is judged, as long as so LDW alarms will be occurred by detecting automobile lane change, there is serious wrong report row
For, it is difficult to popularization and application.On how to determine whether normal lane change behavior, Mobileye in ADAS systems
Scheme be to disassemble automobile component, break line access vehicle interior CAN, further according to turn signal state come
Judge whether be driver active behavior, this mode has following defect：First of all, it is necessary to disassemble electricity
